The diagram shows the position of Earth and four positions of the moon during one orbit of Earth.

1.) Draw an X to show where the sun would need to be located to create the moon phases shown. (Notice the light and dark sides)

2.) Which letter (A, B, C, or D) on the diagram shows the position of the moon when an observer on Earth sees the Full Moon?

3.) Label the Moon phases that are Waxing and Waning. (Note the direction of the arrows on the diagram)
